Jonathan Coveney commented on PIG-2619:
---------------------------------------
Good catch, Andy! I assume that the feature is used in normal HBase operations,
just counterproductive in MR jobs?
> HBaseStorage constructs a Scan with cacheBlocks = false

> Per <http://hbase.apache.org/book/mapreduce.example.html>, Scan objects for
> map-reduce jobs should disable cache blocks.
> scan.setCacheBlocks(false); // don't set to true for MR jobs
> This issue and the attached patch does so for Pig's HBaseStorage.
